Application filed October 6, 1896.

To all whom it may concern.-

Be it known that we, WILLIAMA. PHIL- POTT, J r., of Niagara Falls, inthe county of Niagara, in the State of New York, and

5 THOMAS A. BRIGGS, of Arlington, in the county of Middlesex, in the.State of Massa chusetts, citizens of the United States, have inventednew and useful Improvements in Paper-Feeding Machines, of which thefollowing is a specification.

This invention relates to that class of sheetpaper-feeding machines inwhich the sheets are combed out and the top sheet is separated from thepile of sheets by a rotary combwheel, such a machine being shown, forinstance, inPatent No. 538,640, granted to us April 30, 1895.

The objects of our invention are to improve the means whereby the sheetsare fed from the upper supply to the lower feed-table, to render themachine capable of straightening or squaring the sheets transversely onthe feed-table, to permit of easily adjusting the machine to differentsizes of sheets, to provide means for preventing; the sheets from beingfed too rapidly against the front guides of the press and injured, torender the sideregistering mechanism easily reversible for registeringthe sheets from either side, and to improve and simplify theconstruction of the machine in several details.

In the accompanying drawings, consisting of four sheets, Figure 1 is ahorizontal section of our improved paper-feeder in line 1 1, 5 Fig. 2.Figs. 2 and 3 are vertical longitudinal sections in lines 2 2 and 3 3,Fig. 1, respectively. Figs. 4 and 5 are fragmentary verticallongitudinal sections in lines 44 and 5 5, Fig. 11, respectively. Fig.6is an end elevation of our improved paper-feeder.

Like letters of reference refer to like parts in the several figures.

A represents the impression-cylinder of a printing-press provided withthe usual grippers a, B the lower feed board or table arranged with itsdelivery end over the cylinder, and C the vertically-movable frontregistering-guides arranged over the cylinder and at the delivery end ofthe lower feed- D is the upper feed or supply table,arranged at asuitable height above the lower table and secured to a frame 61, whichis pivoted at its delivery end by a transverse rod d to standards orframes E E, mounted on the front or receiving portion of the lowertable.

The central and rear portions of the upper table are supported on eachside by a pair of braces e e, pivotally connected at their upper ends tothe supporting-frame d and pivotally connected at their lower ends withthe adjacent standard by a link 6 F represents the feed-belts wherebythe body of the sheet-paper is carried from the upper supply-table tothe lower feed-table and which pass, with their receiving portions,around rollers g, arranged on the rear portion of the su pply-table,thence forwardly over the supply-table, thence downwardly and rearwardlyaround feed-wheels G, which are 8 5 arranged between the delivery end ofthe upper table and the receiving end of the lower ta blc, thenceupwardly and rearwardly around supporting-rollers g, mounted on theunder side of the upper table,,and thence rearwardly to the place ofbeginning The pile of sheets is placed on the supply-table and thecarrying portions of the belts, with the top of the pile tipped orcombed rearwardly or toward the printing-press, and the front or bottomportion of the pile is carried downwardly by the feed wheels and beltsto the lower feedtable and moved forwardly over the latter in anopposite direction from that in which it moves on the upper table,whereby the position of the sheets is reversed and the bottom sheet ofthe pile is arranged uppermost on the lower table. The feed-wheels aresecured to a hollow transverse shaft 9 j on rnaled with its ends oncylindrical bushings g", which are secured in openings in the standardsE.

H represents a number of curved guidebands, which bear against the bodyof sheetpaper as it passes around the feed-wheels and which guides thepaper from the feed-wheels to the lower table. The lower ends of thesebands rest on the lower table and their upper ends are secured tohangers h, which are pivoted on a cross-bar 7L, connecting thestandards. The hangers of the outer guide-bands are provided withweighted arms 7L2, whereby the bands are pressed against the paper forincreasing the frictional contact between the paper and the feed beltsand wheels.

The construction and operation of all of the parts in theforegoin gdescription are substantially the same as in Patent No. 538,640,heretofore referred to.

I represents pressure wheels or rollers whereby the body of sheets ispressed against some of the feed wheels and belts, so as to render thecarrying effect of the belts and wheels more positive. One of theserollers is arranged above each of the inner feed-wheels and projectsthrough a slot 1 formed partly in the adjacent guide-band and the flangeof its supporting-hanger. The pressing-rollers are secured to atransverse shaft 71, journaled in the free front ends of rock-arms *3,which are hung on the cross-bar 7L and which permit the pressure-rollersto move toward and from the feed-wheels to adapt themselves to thevariations in the thickness of the body of paper. The pressure-rollersare positively rotated in the direction of the arrow, Fig. 2, so as toaid in feeding the paper by means of a chain belt j, passing around alower sprocket-wheel j, secured to one end of the feed-whee1shaft,and anuppersprocket-wheel 7' journaled on the cross-bar'h, and intermeshinggear-wheels 7' 3' secured, respectively, to the upper sprocket-wheel jand one end of the pressure-roller shaft 2'.

K K represent rotary bushing or combing wheels, which bear with theirlower portions upon the sheets lying on the lower feed-table near theopposite side edges thereof and which comb out or separate the body ofsheets and feed the top sheet toward the printing-press considerably inadvance of the next lower sheet. Each of these combing-wheels is rotatedintermittently and independent of the other wheel by the followingmechanism:

L represents a short counter-shaft arranged parallel with and in rear ofthe feed-wheel shaft 9 and journaled with its outer end in a bearing inthe adjacent standardand with its inner end in a bearing formed in abracket Z, which is hung on the feed-wheel shaft and the cross rod orbar 61. Z is a hollow r0ckarm, which is hung at one end on thecountershaft and provided at its opposite free end with a bearing inwhich the shaft is of the comb wheel is journaled. Motion is transmittedfrom the counter-shaft to the combwheel shaft by gearing which isarranged in the hollow arm and which consists of two gearwheels Z 1secured, respectively, to the counter-shaft and comb-wheel shaft and twointermeshing gear-wheels Z Z, which are journaled in the hollow arm andmesh, respec tively', with the gear-wheels of the countershaft and thecomb-wheel shaft. Z is an idler gear-wheel journaled on an arbor securedto the outer side of one of the standards and meshing on one side with agear-wheel Z secured to the outer end of the countenshaft and with itsopposite side with a gear-wheel Z which is journaled on one of thebushings 9 secured to the adjacent standard. M represents a contin uously-rotatin g driving-shaft which is arranged in the hollow feed-wheel,-

shaft g and journaled concentrically in the bushings g The drivingmechanism of each comb-wheel is connected with and disconnected from thedriving-.shaft by a coupling device of any suitable construction, thepreferred form of coupling for this purpose beingan electromagneticclutch which is shown in Figs. 13, 14c, and 15 and constructed asfollows:

N is a clutch-disk, of soft iron, journaled on one of the bushings g andprovided with a peripheral groove which contains a coil of insulatedwire n. The clutch-disk is connected with the adjacent gear-wheel Z andis provided on its hub with two insulated metal collectin -rin s n nwhich are connected, re-

spectively, with opposite ends of the coil of .wire a. 91 11 are twoinsulated brushes which bear,respectivcly,against the collecting-rings nn and which are in the circuit of an electric current. 1 Q is aclutch-wheel secured to the driving-shaft adjacent to the outer side ofthe clutch-disk and provided with a peripheral flange which overhangsthe clutch-disk. 0' represents a number of clutch-shoes, of soft iron,arranged between .the flange of the clutch-wheel and the periphery ofthe clutchdisk, each shoe being loosely connected with the clutch-wheelby a radial pin 0 secured to the flange of the clutch-wheel and engagingin a recess in the shoe, whereby the latter is compelled to turn withthe clutch-wheel, but capable of moving'radially toward and from theface of the clutch-disk. YVhen the electric circuit which includes thecoil of the clutch-disk is broken, the clutch-shoes are thrown outwardlyby the rotation of the clutch-wheel and out of engagement with theclutch-disk, whereby the latter is disconnect- -ed from thedriving-shaft and the movement of the comb-wheel is arrested. Theinstant the electric circuit is closed the clutch-disk becomesmagnetized and draws the clutchshoes against 'its periphery withsufficient force to couple-the clutch disk and wheel,

thereby causing the movement of the drivingshaft to be transmitted tothe comb-wheel through the medium of theintermediate conmeeting-gearing.

The feed wheels and belts are moved intermittently in unison with thecomb-wheels by the following mechanism.

P represents a ratchet-Wheel which is secured to one end of thefeed-wheel shaft adjacent to the inner side of one of the standards E.Q, is a feed-pawl carrier which is mounted on the rim of theratchet-wheel and which consists of two side plates q and a transverseplate or body q, connecting the side plates. The inner side of each sideplate is provided with a curved groove (1 Fig. 16, the two grooved sideplates forming jaws which loosely embrace the opposite curved edges ofthe ratchet-wheel rim, as represented in Fig. 13, whereby thepawl-carrier is held against lateral and radial movement on theratchet-wheel, but is capable of sliding circumferentially thereon. Thefeed-pawls g Figs. 12 and 14, are pivoted to the front or upper ends ofthe side plates and are-yieldingly held in engagement with the teeth ofthe ratchet-wheel by a spring (1 secured to the transverse plate. Thepawl-carrier is arranged on the rear side of the ratchet-wheel, so thatit has substantially a vertical movement and permits the return ordownward movement thereof to be efiected by gravity without the aid ofsprings. This manner of supporting the feed-pawls is extremely simpleand inexpensive and is not liable to bind and get out of order. R is arotary feed-cam which engages with a roller g on the rear or lower endof the pawl-carrier for moving the latter forward and turning thefeed-wheels and which is journaled on an arbor q", secured to the innerside of-the adjacent standard. The feed-cam is turned by intermesh inggear-wheels '1" r secured, respectively, to the counter-shaftand thefeed-cam R, Figs. 13 and 14. 0' is an adjustable stop, whereby theeffective or feeding movement of the pawlcarrier can be regulated. Thisstop consists of a rotary plate mounted loosely on the counter-shaft andprovided with an eccentric or cam-shaped stop-face 0", against which ashoulder '1' on the back of the pawl-carrier is adapted to engage forlimiting the backward movement of the pawl-carrier. The latter is alwaysmoved forward to the same point by the feed-cam; but its backwardmovement can be varied by turning the adj nstable plate so that a higheror lower part of its stop-face engages with the shoulder of thepawl-carrier, whereby the extent of the effective movement of thepawl-carrier is varied. The stopplate is provided with a thumb-piece rfor adjusting the same and is held in its adjusted position by aclamping-screw 1, arranged in a bracket on the adjacent standard. Srepresents a detent-pawl carrier which is mounted on the upperportion ofthe ratchet-wheel and which consists of two side plates. 8, to

which the detent-pawls s are pivoted, and a transverse plate 3connecting the side plates. The side plates are provided on their innersides with curved grooves, forming jaws which loosely embrace theopposite edges of the ratchet-wheel rim in the same manner in which thefeed-pawl carrier is mounted on the ratchet-wheel. The detent pawls areyieldingly held in engagement with the teeth of the ratchet-wheel by aspring 3 secured to the detent-pawl carrier. When it is desired toutilize the detent-pawl to prevent backward movement of theratchet-wheel, the detent-pawl carrier is held against movement on theratchet-wheel by means of a spring 8 which is secured to the transverseplate 3 and which is provided with a seat 8 engaging with the cross-bar71. Upon disengaging the spring 8 from the rod h the detent-pawl carriercan be oscillated on the rim of the ratchet-Wheel by means of a handle 8for adjusting the paper in the machine preparatory to starting theautomatic feeding of the sheets.

Each sheet as it is fed by the comb-wheels over the lower feed-tabletoward the printin g-press passes between two pair of contacts, whichare arranged to engage with the front edge of the sheet near theopposite front corners thereof. Each pair of contacts consist,

preferably, of a lower metal roller 25, which is journaled in the lowerfeed-table below the path of the sheets, and an upper metal roller 15,which is yieldingly held in contact with the lower roller. nected by awire i with one pole of an electric generator T, the other pole of whichis connected by a wire 15 with the brush n of one of the electricclutches. t is a metal supporting-rod, to the lower end of which theupper contact-roller is pivotally connected by a metal link (5, and t isa spring secured at one end to said rod and bearing with its oppositeend against the link for keeping the upper roller t in contact with thelower roller 25. The lower contact or its support is connected by a wire15 with the other brush n of the aforesaid electric clutch. i is atransverse supporting-bar which carries the supporting-rods t of bothupper contacts and which is secured by insulation at its ends tostandards '6 arranged on the lower feed-table. When both uppercontact-rollers bear against both lower contact-rollers, the electriccircuits of both clutches are closed and both comb-wheels are coupledwith the drivingshaft, which causes both comb-wheels to rotate and feeda sheet forwardly. When the comb-wheels leave the rear edge or margin ofthe top sheet, the front edge of the latter hasbeen moved between theupper and lower rollers of both contacts and the paper servingas aninsulator breaks both electric circuits, thereby uncoupling bothclutches and arresting the movement of both comb-wheels and the forwardfeed of the sheets. If a sheet is fed forward obliquely, the foremostcorner of The upper contact is conthe sheet passes between one pair ofcontacts and arrests the movement of the comb-wheel which feeds thatside of the sheet, while the other comb-wheel continues to rotate untilthe opposite side of the sheet has also been fed forward until its frontedge also separates the other pair of contacts. By this means anyirregularity in the feeding of the sheets iscorrected and the sheets arealways squared or straightened on the feed-table. After the front edgeof the sheet has separated the contacts of both pairs and has arrestedthe movement of the comb-wheels the sheet is carried toward the press bya separate carrying device, and when the rear edge of the sheet clearsthe contacts the upper contact-rollers are instantly pressed against thelower contact-rollers and the feeding movement of the comb-wheels andfeed-wheels is resumed until the front edge of the next sheet has beenfed between both pairs of contacts.

The relative position of the comb-wheels and the electric contacts issuch that when the front edge of the top sheet has separated the upperand lower contacts the comb-wheels have cleared the rear edge of the topsheet and bear upon the next sheet below the top sheet to prevent thelower sheet from being carried away with the top sheet. In order topermitof feeding sheets of various lengths, the comb-wheelsare adjustedlengthwise on the lower feed-table toward and from the electric contactsfor adapting the comb-wheels to the sheets. For the purpose ofaccomplishing this result in a simple and expeditious manner thestandards E,upon which the sheetseparating mechanism is mounted, aremade longitudinally adjustable on the lower feedtable. As shown in thedrawings, the lower end of each standard is provided with a foot orflange u on its inner side, which slides on a longitudinal rail or track11/, secured to the top of the lower feed-table, and the rail isprovided with an angular retaining-bar a which overhangs the foot of thestandard, whereby the standard is held against displacement on the lowertable. The standards are shifted by means of a transverseadjusting-shaft u journaled in the lower portion of both standards E andprovided adjacent to the inner sides of the standards with gear-pinionsa, which mesh with gear-racks a, secured lengthwise to the top of thefeedtable. One end of the adj listing-shaft is provided with ahand-wheel 11 for turning this shaft, and the inner side of one of thestandards is provided with a retaining-pawl 11. which is adapted toengage with one of the gear-pinions u and hold the adjustingshaftagainst turning after the parts are adjusted. It has been found inpractice that the comb-wheels must be placed sufficiently near to thefeed-wheels to enable the combwheels to obtain control of the sheetsbefore pose the comb-Wheels are placed near enough to the feed-wheels toretain control of the narrowest sheets, which are intended to be fed bythe machine. By shifting the feedwheels, together with the comb-wheels,the relative position of these parts is never disturbed, and a simpleand non -adjustable drive mechanism can be employed for driving thecon1b-wheels,which insures transverse alinernent of both comb-wheels atall times without any care on the part of the operator.

V represents two rapid] yrotating feed-rollers, which rotate at aboutthe rate of six revo lutions to one of the impression-cylinder, andwhereby each sheet is carried toward the printing-press after its frontedge has been fed between the electric contacts by the combwheels. Theserollers are mounted on acoutinuously-rotating shaft "0, which isjournaled in bearings on the under side of the feedtable and protrudeupwardly through openings in the feed-board adjacent to the contacts, sothat their uppermost portions are in line with the top of the table. nare two presser or drop rollers arranged above the feed-rollers V andhaving a vertical movement toward and from the feed-rollers. Each ofthese presser-rollers is mounted on a forwardly-projecting rock-arm 0which is secured to a transverse rock-shaft v journaled in the standardst. The pressure-rollers are raised and lowered once during eachimpression of the printing-cylinder. During the time that the sheet isbeing fed forward to the electric contacts the presser-rollers areelevated, and after the sheet has been fed between the contactsthe'drop-rollers descend and press the sheet against the feed-rollers,whereby the latter are caused to carry the sheet rapidly toward thedrop-guides of the printing-press. When the sheet has been fed forward asufficient-distance by the feed-rollers, the presser-rollers are againraised. The means shown in the drawings for raising and lowering thepresser-rollcrs consist of a vertical bar or rod 1:, connected at itsupper end to a rearwardly-proj ectin g rock-arm c on the rock-shaft andacam 0 engaging with a roller or projection on the lower end of said rod.This cam is mounted on a counter-shaft Q77, which is journaled inbearings on the under side of the feed-table and which is driven fromthe shaft of the feed-rollersV by a train of speed-reducing gear-wheelsc In order to prevent the sheets from being fed by the rapidly-rotatingfeed-rollers V against the front or drop guides with a speed su'fficientto injure the front edge of the sheets, the speed of the latter as theyapproach the drop-guides is reduced or slackened by a retardingmechanism, which is constructed as follows:

W represents two eccentric rollers, which are mounted on a transverseshaft to, journaledin bearings on the under side of the feed-table andwhich are adapted to protrude upwardly through openings to in thefeedtable.

These eccentric rollers are rotated once during each impression of theprintingcylinder in any suitable manner--for instance, by means of achain belt passing around sprocket-wheels 10 mounted, re-

spectively, on the counter-shaft v and the eccentric roller-shaft. 10represents two abutment-rollers, which are arranged above the path ofthe sheets vertically in line with the eccentric rollers and againstwhich each sheet is pressed by the eccentric rollers during the lastportion of the movement of the sheet toward the front dropguides. Eachof the abutment-rollers is mounted on the rear arm of an adjusting-lever to, which is pivoted on a transverse arbor .10 secured to alongitudinal supporting-plate 10 as shown in Figs. 9 and 10. Theabutment-roller is yieldingly held in a depressed position by a springw,

. surrounding the arbor w and secured with its ends to theadjusting-lever, and a rotary thumb-piece 10 mounted on the end of thearbor. The extent of the downward move ment of the abutment-roller isregulated by means of an ad justing-screw 10 which bears against theupper side of the front arm of the adj listing-lever and which engageswith a screw-threaded opening formed in a lug arranged on thesupporting-plate. The instant the drop-rollers are raised, so that thesheet clears the rapidly-rotating feed-rollers, theslowly-rotatingeccentric rollers begin to press the sheet against theabutment-rollers,whereby the speed of the sheet is checked and the sheetis fed slowly against the front guides without kinking the front edgethereof. As the eccentric rollers bear against the abutment-rollers thelatter rise and fall in adj usting themselves to the peripheral faces ofthe eccentric rollers, which movement of the abutment-rollers ispermitted by their yielding supports. Upon adjusting theabutment-rollers upwardly, so as to increase the distance between thesame and the eccentric rollers, the peripheral faces of the latterremain during each rotation in contact with the abutment rollers acomparatively short time, whereby the sheets are acted uponby theeccentric and abutment rollers only during a short part of theirmovement. When the abutment-rollers are adjusted toward the eccentricrollers, the duration of contact be tween the sheets and the abutmentand eccentric rollers is increased and the sheets are fed forward bythese rollers a correspondingly greater distance, so that by adjustingthe abutment-rollers with reference to the eccentric rollers thecarrying effect of these rollers can be regulated for feeding sheets ofdifferent widths properly to the front guides. Each of thesupporting-plates is .secured to a longitudinal supporting-rod 10 whichis hung with its front end on the cross-bar t and secured with its rearendto a transverse supporting-bar 10 The latter is supported at its endsby means of posts 20, arranged on the feed-table.

X X represent two side-registering devices whereby the sheet may beside-registered on either of its side edges and which are arranged onthe feed-table on opposite sides of the path of the sheet. Theseside-registering devices are provided with side guides m at, againsteither of which the sheets are d rawn by a transversely-reciprocatin gcarrierbar 00 that operates the gripping devices. The construction andoperation of this sideregistering device are fully described in LettersPatent No. 562,797, granted to us June 30, 1896, to-which reference maybe had for the details of construction. In the operation of thisside-registerin g mechanism the gripper adjacent to that side of thesheet on which the latter is to be registered is first moved inwardly oraway fromthe side guide and is then moved outwardly, during which lattermovement the working gripper grasps the sheet and draws its side edgeagainst the registerin g side guide. If it is desired to change theregistering of the sheets from one side to the other, the movement ofthe carrier-bar must be altered, so that its first or inward movementwill be away from the registering side guide, and for the purpose ofenabling the operation of the side-registering mechanism to be readilyand accurately shifted for changing the register of the sheets from oneside to another the following mechanism is provided:

Y represents a vertical rock-spindle, which is journaled in a bracket y,secured to the under side of the feed-table and which is provided at itsupper end with a crank-disk 11 g is a connecting-rod pivoted at one endto a crank-pin g on the crank-disk and pivoted with its opposite end toa pin 11", which is secured to the under side of the carrier-bar andprojects downwardly through a slot 11 in the feed-table. y is agear-pinion which is mounted loosely on the spindle and confined againstlongitudinal movement on the spindle by shoulders formed on the bracketon opposite sides of the pinion. 1 is a horizontal reciprocatinggear-rack guided on the bracket and meshing with the outer side of thegear-pinion. This gear-rack is actuated from a cam 3 on thecounter-shaft o by a connectingrod g, which is pivoted at its rear endto the gear-rack and provided at its front end with a roller or pin 11engaging with the camgroove y and with a slot 1 whereby theconnecting-rod is guided on the counter-shaft. 2 represents acoupling-sleeve whereby the spindle and the gear-pinion are coupled andwhich surrounds the spindle below the pinion and is journaled in theadjacent portion of the bracket. This sleeve is capable of lengthwisemovement on the spindle, but is compelled to turn therewith by means ofa transverse pin 2, secured to the spindle and engaging withlongitudinal slots in diametrically opposite sides of the lower end ofthe coupling-sleeve. .2 is a pin arranged at the inner end of thecoupling-sleeve and engaging with one of two recesses or openings 23,

which are formed in the underside of the pinion on diametricallyopposite sides thereof. This pin is yieldingly held in engagement withone of the openings in the pinion by means 'of a spring .2 whichsurrounds the spindle within the enlarged lower portion of thecoupling-sleeve and bears with its ends against a shoulder on thecoupling-sleeve and a collar 2 on the lower end of the spindle.

.Figs. 4, '7, 8, and 11 show the position of the parts of theside-registering mechanism preparatory to beginning the operation ofregistering a sheet on the left-hand edge. Before the sheet has been fedagainst the front guides the cam 3 first. moves the gear-rack, pinion,carrier-bar, and connecting parts forward in the direction of thearrows, Figs..1. 4, 7, 8, and 11, and after the sheet has been fedagainst the front guides the cam moves these parts backward and thesheet is carried outwardly by the gripper of the registering device Xagainst the registering-guide The registering mechanism now remains atrest until the registered sheet has been carried away by the grippers ofthe press. \Vhen registering the sheets on the left-hand edge, thecrankpin on the crank-disk moves in an are on the rear portion of thedisk from the point .2 to the point 2 and then back again to the pointe, as shown in Fig; 11.. When it is desired to reverse the movement ofthe registering outwardly for carrying the right-hand edge of the sheetagainst the side guide X. This change in the register of the sheet fromone side to the other is accomplished by pulling the couplingsleevedownwardly until its pin is disengaged from the respective recess in thegear-pinion, then turning the couplingsleeve, spindle, and crank-diskone half around independent of the gear-pinion, and then releasing thecoupling-sleeve, so that its pin engages with the other recess of thepinion, whereby the connecting-rod, carrier-bar, and connecting partsare shifted into the proper position for reversing the side-register ofthe sheets.
